Sorry if this was posted already somewhere, but I'm leveling my priest, I just hit 78 and crafted 6 pieces of frostsavage gear and have dual spec disc and shadow, both for pvp. If I plan on doing a mix of shadow and disc for PvP at 80, I was wondering if the relentless/wrathful 4 piece bonus of shaving 2 seconds off of weakened soul debuff is better than just getting 2 pieces of mooncloth and 3 pieces of satin (or 3 moon/ 2 satin), so you get the extra 100 resilience from having both sets 2 piece bonus, plus I would have a mix of spirit and crit for both specs?
